RestSharp - could not be found

Question

I have looked at other questions posted about this but nothing seems to answer my question/problem. Hopefully because my question/problem seems like a simple fix if anything.

I installed RestSharp using nuget.

using RestSharp;
using RestSharp.Authenticators;

are underlined with blue

private IRestClient restClient;

is also underlined.

If i restart my IDE, there is no error. I hit build to compile my object.. and all the RestSharp references "disappear." I try to add the reference manually using the RestSharp.dll and it barks at me telling me that there is already a reference to RestSharp

Any other suggestions?

Answer 1

Change the Framework from anything less than 4 up to 4 and recompile.

restsharp was developed and compiled in 4.0
